 Log Message:
 Apply patch in PR kern/44907 (crash due to race in ehci.c):
  - make sure to remove abort_task in ehci_freex
  - always initialize abort_task in ehci_allocx,
    not in ehci_timeout just before adding the task
 Also apply similar fixes to ohci and uhci.
 
 XXX: should we also call abort_task handler before removing it from queue
      if *hci_freex() is called for usbd_xfer_handle with queued abort_task?
